Download of Cyclidic Nets 6.0 was on the developer's website when we last checked. We cannot confirm if there is a free download of this software available. We recommend checking the downloaded files with any free antivirus. The actual developer of the free software is Emanuel Huhnen-Venedey. Cyclidic Nets is categorized as Education Tools.
From the developer:
Cyclidic nets are a discretization of orthogonal nets, closely related to the discretization as circular nets. In Euclidean 3-space they discretize curvature line parametrized surfaces resp. triply orthogonal coordinate systems. The application allows to extend (fixed) 2- and 3-dimensional circular nets to cyclidic nets, where the extension is uniquely determined by the choice of an orthonormal 3-frame at one vertex.
You may want to check out more software, such as Net Core PDF Generator, VB.Net Excel Library or FlyGrid.Net Evaluation, which might be similar to Cyclidic Nets.
